[PATCH 1/2] nfsmount.conf: Remove duplicate 'bg' and 'fg' from parsing string.

[Steve Dickson <steved@redhat.com>]

When the 'Background' and/or 'Foreground' options are set
in multiple sections of the nfsmount.conf file, each instance
gets added to the parsing string. This patch makes the first
instance of either option override the any others.
